Hi, I have been suffering with hay fever for a number of years but recently it has been really bad. So much so that the medication I take such as citrizen,loratadine and fexofenadine so not work a single bit despite being on the strongest dose. I have been getting to the point where I feel really weak, get really bad shakes and really sweaty to the point where I m nearly passing out. Is there anything you could recommend? Cheers Ryan
